Please note, inline with the Austroads transition to MASH compliant systems, the Flexfence system may no longer be approved for new installs in your jurisdiction, please consult your local Ingal representative for further information. For a fully compliant MASH TL4 WRSB, please refer to our MashFlex system.
The superior design and clean lines of Flexfence Wire Rope Safety Barrier (WRSB) has seen it become the road safety industry’s preferred wire rope barrier. Flexfence has gained popularity in median applications, for the prevention of cross-median accidents, and verge applications where the system has proven TL4 containment capabilities with some of the lowest occupant impact severities for any type of safety barrier.
The straight alignment of the cable barrier ropes allows for easy installation and tensioning. Post footings are typically concrete with a sleeve to form a recess. Once the anchors and footings are poured, the ropes are cut to length, stainless steel end fittings are machine swaged and the ropes are tensioned.
Flexfence TL4 has been assessed in accordance with NCHRP Report 350 Test Level 4 (TL4). The TL4 heavy vehicle impacts are performed with a 2,000kg pick-up truck travelling at 100km/h and 25° impact angle, and an 8,000kg rigid truck travelling at 80km/h and 15°.
